Description

Technical Field

[0001] This utility model relates to the field of hot-dip galvanizing technology, specifically to a cooling device for hot-dip galvanizing. Background Technology

[0002] Hot-dip galvanizing is a process in which molten metal reacts with an iron substrate to create an alloy layer, thus bonding the substrate and the coating. The process begins with pickling the steel parts to remove iron oxide from their surface. After pickling, the parts are cleaned in an aqueous solution of ammonium chloride or zinc chloride, or a mixture of both, before being immersed in a hot-dip galvanizing bath. Hot-dip galvanizing results in a uniform coating, strong adhesion, and long service life. Current cooling systems for hot-dip galvanizing typically use a water pump to draw cooling water and then spray it through nozzles to cool the galvanized surface. However, because the nozzle angles are usually fixed, this method can lead to uneven cooling during the hot-dip galvanizing process.

[0003] A search revealed a Chinese patent publication dated March 1, 2024, with publication number CN220550210U, describing a cooling device for hot-dip galvanizing. The device comprises a body with a water tank inside, two guide plates on the top of the tank, a cooling mechanism running through the body, and an adjustment mechanism. An opening is located on the top of the water tank. This invention suspends the hot-dip galvanized steel on hooks at the bottom of a mounting frame. A water pump draws water from the tank through a suction pipe, which then distributes the water through a delivery pipe and a three-way connector to two branch pipes. These branch pipes then direct the water to a spray nozzle, which sprays cooling water onto the hot-dip galvanized steel on both sides. A slow-speed motor rotates a rotating rod, causing the mounting frame, fixed to one end of the rod, to slowly rotate the hooks and the hot-dip galvanized steel on them. This ensures the water sprayed from the nozzles is evenly distributed to the hot-dip galvanized steel, thus improving cooling efficiency.

[0004] Although the above-mentioned existing technical solutions can improve cooling efficiency, the different distances between the multiple hooks on the device and the water spray pipes result in uneven cooling and reduce the cooling effect. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a cooling device for hot-dip galvanizing, which solves the problem of uneven cooling and reduced cooling effect mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for hot-dip galvanizing, comprising a cooling box and a water tank, the water tank being fixedly connected to the bottom of the cooling box. A drain pipe is provided at the bottom of the cooling box, connecting to the interior of the water tank. A geared ring is rotatably connected to the upper inner wall of the cooling box, and multiple evenly distributed placement hooks are installed at the bottom of the geared ring. A motor is installed at the top of the cooling box, and the output end of the motor passes through the cooling box and is connected to a gear meshing with the geared ring. A water pump is installed on the outer wall of the water tank. The water pump's inlet is connected to the interior of the water tank, and the water pump's outlet is connected to a first water pipe. One end of the first water pipe is connected to a tee, and a second water pipe and a third water pipe are connected to the tee. One end of the second water pipe passes through the side wall of the cooling tank and is connected to a first branch water pipe. One end of the third water pipe passes through the top of the cooling tank and is connected to a second branch water pipe. Both the second and first branch water pipes have multiple evenly distributed nozzles at their respective ends. The first branch water pipe is located on one side of the toothed ring, and the second branch water pipe is located in the middle of the toothed ring.

[0009] By adopting the above technical solution, hot-dip galvanized steel is placed on the placement hooks. A water pump is started, driving water from the tank through the first water pipe into the second and third water pipes, then into the first and second branch water pipes, and finally sprayed out through nozzles to cool the hot-dip galvanized steel. Used water flows back to the tank through a drain pipe for easy recycling. A motor is started, driving a gear to rotate, which in turn drives a gear ring to rotate. The gear ring then drives multiple placement hooks to rotate, and the placement hooks drive multiple hot-dip galvanized steel pieces to rotate between the first and second branch water pipes. This ensures that the distance between the hot-dip galvanized steel pieces and the first and second branch water pipes is the same during cooling, thus achieving uniform cooling and improving the cooling effect.

[0010] Optionally, a placement frame is fixedly connected to the inner wall of the cooling box, and a filter plate is placed on the top of the placement frame. The top of the filter plate is provided with two handles.

[0011] By adopting the above technical solution, the filter plate is used to filter the water falling from the hot-dip galvanizing, preventing impurities from flowing back into the water tank and causing damage to the water pump, thus improving the stability of the equipment. The handle is used to facilitate personnel to pick up and put down the filter plate.

[0012] Optionally, the lower inner wall of the cooling box is fixedly connected with a guide that cooperates with the drain pipe.

[0013] By adopting the above technical solution, the guide component is used to guide the used water, thereby facilitating the water flow to the drain pipe and reducing water residue in the cooling tank.

[0014] Optionally, the rear end of the water tank is provided with heat sinks, and a fan that cooperates with the heat sinks is installed at the rear end of the water tank.

[0015] By adopting the above technical solution, the heat sink is used to facilitate the dissipation of heat from the water in the water tank, and the fan is used to improve the airflow near the heat sink, thereby improving the heat dissipation effect and avoiding a reduction in the cooling effect of hot-dip galvanizing due to overheating of the water.

[0016] Optionally, the water tank is provided with a transparent observation window, and the water tank is provided with a water inlet pipe, which is provided with a rubber stopper.

[0017] By adopting the above technical solution, the transparent observation window is used to facilitate personnel to observe the water level in the water tank. When the water level is too low, it is easy to add water in time through the water inlet pipe to avoid water shortage.

[0018] (III) Beneficial Effects

[0019] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] This hot-dip galvanizing cooling device places the hot-dip galvanized zinc galvanizer on the placement hooks. A water pump is activated, drawing water from the tank through a first water pipe into the second and third water pipes, then into the first and second branch water pipes, and finally spraying it out through nozzles to cool the galvanized zinc galvanizer. Used water flows back to the tank through a drain pipe for easy recycling. A motor drives a gear, which in turn drives a gear ring, which in turn drives multiple placement hooks. These hooks then rotate multiple hot-dip galvanized zinc galvanizers, ensuring that the distance between the galvanized zinc galvanizer and the first and second branch water pipes is the same during cooling, thus achieving uniform cooling and improving the cooling effect.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-4A cooling device for hot-dip galvanizing includes a cooling box 1 and a water tank 2. The water tank 2 is fixedly connected to the bottom of the cooling box 1. A drain pipe is provided at the bottom of the cooling box 1, and the drain pipe connects to the interior of the water tank 2. A gear ring 3 is rotatably connected to the upper inner side wall of the cooling box 1. Multiple evenly distributed placement hooks 4 are installed at the bottom of the gear ring 3.

A water pump 7 is installed on the outer wall of the water tank 2. The inlet end of the water pump 7 connects to the interior of the water tank 2. The outlet end of the water pump 7 is connected to a first water pipe 8. One end of the first water pipe 8 is connected to a tee 9. A second water pipe 10 and a third water pipe 11 are connected to the tee 9. One end of the second water pipe 10 passes through the side wall of the cooling box 1 and is connected to a first branch water pipe 12. One end of the third water pipe 11 passes through the top of the cooling box 1 and is connected to a second branch water pipe 13. The second branch water pipe 13 and the first branch water pipe 12 are mutually connected. Multiple evenly distributed nozzles 14 are provided at one end. The first water distribution pipe 12 is located on one side of the gear ring 3, and the second water distribution pipe 13 is located in the middle of the gear ring 3. The hot-dip galvanized steel is placed on the placement hook 4. The water pump 7 is started to drive the water in the water tank 2 to enter the second water pipe 10 and the third water pipe 11 through the first water pipe 8, and then enter the first water distribution pipe 12 and the second water distribution pipe 13. Finally, it is sprayed out through the nozzles 14 to cool the hot-dip galvanized steel. The used water flows back to the water tank 2 through the drain pipe to facilitate recycling. The motor 5 is started to drive the gear 6 to rotate. The gear 6 drives the gear ring 3 to rotate. The gear ring 3 drives multiple placement hooks 4 to rotate. The placement hooks 4 drive multiple hot-dip galvanized steel to rotate between the first water distribution pipe 12 and the second water distribution pipe 13. When the equipment cools the hot-dip galvanized steel, the distance between the hot-dip galvanized steel and the first water distribution pipe 12 and the second water distribution pipe 13 is the same, so as to facilitate uniform cooling and improve the cooling effect.

[0029] Reference Figure 3 and Figure 4 A placement frame 15 is fixedly connected to the inner wall of the cooling box 1. A filter plate 16 is placed on the top of the placement frame 15. Two handles 17 are provided on the top of the filter plate 16. The filter plate 16 is used to filter the water falling from the hot-dip galvanizing, to prevent impurities from flowing back into the water tank 2 and causing damage to the water pump 7, thereby improving the stability of the equipment. The handles 17 are used to facilitate personnel to pick up and put down the filter plate 16.

[0030] Reference Figure 4 The lower inner wall of the cooling tank 1 is fixedly connected with a guide 18 that cooperates with the drain pipe. The guide 18 is used to guide the used water so that the water can flow to the drain pipe and reduce the water residue in the cooling tank 1.

[0031] Reference Figure 2The rear end of the water tank 2 is provided with a heat sink 19, and a fan 20 that works with the heat sink 19 is installed at the rear end of the water tank 2. The heat sink 19 is used to facilitate the dissipation of heat in the water in the water tank 2, and the fan 20 is used to increase the airflow near the heat sink 19, thereby improving the heat dissipation effect and avoiding the reduction of the cooling effect on hot-dip galvanizing due to overheating of the water.

[0032] Reference Figure 1 The water tank 2 is equipped with a transparent observation window 21 and a water inlet pipe 22, with a rubber stopper on the water inlet pipe 22. The transparent observation window 21 is used to facilitate personnel to observe the water level in the water tank 2. When the water level is too low, it is convenient to add water in time through the water inlet pipe 22 to avoid water shortage.

[0033] In summary, the working principle and process of this hot-dip galvanizing cooling device are as follows: First, the hot-dip galvanized zinc plating is placed on the placement hooks 4. Then, the water pump 7 drives the water in the water tank 2 through the first water pipe 8 into the second water pipe 10 and the third water pipe 11, followed by the first branch water pipe 12 and the second branch water pipe 13. Finally, the water is sprayed out through the nozzles 14, thus cooling the hot-dip galvanized zinc plating. Used water flows back to the water tank 2 through the drain pipe, facilitating recycling. The motor 5 drives the gear 6 to rotate, which in turn drives the gear ring 3 to rotate. The gear ring 3 then drives multiple placement hooks 4 to rotate, causing multiple hot-dip galvanized zinc platings to rotate and pass between the first branch water pipe 12 and the second branch water pipe 13. This ensures that the distance between the hot-dip galvanized zinc plating and the first and second branch water pipes 12 is the same during cooling, thus facilitating cooling. The purpose of uniform cooling and improved cooling effect is to filter the water falling from the hot-dip galvanizing tank 16, preventing impurities from flowing back into the water tank 2 and causing damage to the water pump 7, thus improving the stability of the equipment. The handle 17 is used to facilitate personnel to pick up and put down the filter plate 16. The guide 18 is used to guide the used water, so that the water can flow to the drain pipe and reduce the amount of water residue in the cooling tank 1. The heat sink 19 is used to facilitate the dissipation of heat from the water in the water tank 2. The fan 20 is used to improve the airflow near the heat sink 19, thereby improving the heat dissipation effect and preventing the cooling effect of hot-dip galvanizing from being reduced due to overheating of the water. The transparent observation window 21 is used to facilitate personnel to observe the water level in the water tank 2. When the water level is too low, it is easy to add water in time through the water inlet pipe 22 to avoid water shortage.
